Detection and Storage of Errors

ABSTRACT

In one or more embodiments, an embedded controller of the information handling system may detect an error associated with an information handling system before an operating system, executable via a processor of the information handling system, is operable to provide information associated with the error. The embedded controller may store the information associated with the error via a memory medium. The embedded controller may receive a query from operating system executing via the processor. The embedded controller may provide the information associated with the error to the operating system. In one or more embodiments, the embedded controller may detect another error after the operating system is executing and may provide providing information associated with the other error to the operating system upon detection of the other error.

BACKGROUND Field of the Disclosure

This disclosure relates generally to information handling systems and more particularly to detecting and storing errors associated with information handling systems.

Description of the Related Art

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

In the past, when an information handling system performed a power-on self-test and/or a boot sequence, any error information during the power-on self-test and/or the boot sequence would be displayed via a screen. If a user was not viewing the screen during that period, the error information would be lost. Further, after an operating system was executing, a login screen may prevent a user viewing any error information. Moreover, a playback of multiple errors was not available.

SUMMARY

In one or more embodiments, one or more systems, methods, and/or processes may detect an error associated with an information handling system before an operating system, executed via a processor of the information handling system, is operable to provide information associated with the error. Information associated with the error may be stored, and the information associated with the error may be provided to the operating system when the operating system is operable to provide the information associated with the error. Further, a query may be received from the operating system, and the information associated with the error may be provided to operating system in response to the query from the operating system. In one instance, the operating system may utilize a management information exchange, which may include a Windows Management Interface (WMI). In another instance, the operating system may utilize a management information exchange, which may include a Common Information Model (CIM). In one or more embodiments, another error may be detected after the operating system is executing, and information associated with the other error may be provided to the operating system upon detection of the other error.

DETAILED DESCRIPTION

In the following description, details are set forth by way of example to facilitate discussion of the disclosed subject matter. It should be apparent to a person of ordinary skill in the field, however, that the disclosed embodiments are exemplary and not exhaustive of all possible embodiments.

As used herein, a reference numeral followed by a letter refers to a specific instance of an element and the numeral only form of the reference numeral refers to the collective element. Thus, for example, device ‘12A’ refers to an instance of a device class, which may be referred to collectively as devices ‘12’ and any one of which may be referred to generically as a device ‘12’.

In one or more embodiments, one or more errors may be detected before an operating system (OS) is executing and/or before a user logs into an information handling system (IHS). For example, the one or more errors may be detected via a power-on self-test (POST), among other diagnostics and/or system checks. For instance, information associated with the one or more errors may be lost or may not be noticed unless stored and presented after at least one of the OS is executing and the user logs in, among others. In one or more embodiments, the IHS may include a device (e.g., an embedded controller) that may receive the information associated with the one or more errors and store the information for later retrieval and/or presentation. For example, the device of the IHS may store the information associated with the one or more errors via a memory medium, receive one or more queries from the OS or an application (APP), and provide the information associated with the one or more errors to the OS or the APP in response to the one or more queries. In one instance, a playback of information associated with one or more errors and/or events may be provided to one or more of the OS and the APP, among others. In another instance, a playback of information associated with all errors and/or events may be provided via a user interface (e.g., provided to a user via the user interface). In one or more embodiments, at least one of the one or more errors may no longer exist and/or may no longer be an issue. For example, if the at least one of the one or more errors no longer exists and/or is no longer an issue, the device of the IHS may remove and/or delete information associated with the at least one of the one or more errors.

In a second example, one or more portions of EC data 276 may be transferred to volatile memory medium 250, and processor 220 may utilize EC data 276 via volatile memory medium 250. In a third example, processor 220 may store one or more statuses via EC data 276. For instance, processor 220 may store one or more error conditions determined via a power-on self-test (POST). In another example, processor 220 may provide the one or more statuses to OS 162 that were stored via EC data 276. For instance, processor 220 may provide information associated with the one or more error conditions, determined via the POST, to OS 162.

In one or more embodiments, one or more errors may be detected before OS 162 is executing, is operable to provide error information, and/or before a user logs into IHS 110, among others. In one example, the one or more errors may be detected via a POST. For instance, IHSFW 172 may include the POST. In a second example, IHSFW 172 may detect the one or more errors may be detected outside the POST. In another example, the one or more errors may be associated with device 198. In one example, device 198 may be damaged or otherwise defective or impaired. In another example, a cable coupling device 198 to IHS 110 198 may be damaged or otherwise defective or impaired. In one or more embodiments, EC 190 may receive information associated with one or more errors of IHS 110. For example, EC 190 may receive the information associated with the one or more errors from IHSFW 172.

In one or more embodiments, EC 190 may store the information associated with the one or more errors that were detected. For example, EC 190 may store the information associated with the one or more errors via one or more memory media. For instance, EC 190 may store information associated with the error via one or more of volatile memory medium 250, non-volatile memory medium 260, volatile memory medium 150, non-volatile memory medium 160, and non-volatile memory medium 170, among others. In one or more embodiments, EC 190 may store the information associated with the one or more errors via a data structure.

In one or more embodiments, OS 162 may query EC 190 for information associated with any errors that were detected. In one example, OS 162 may utilize MIE 163 to query EC 190 for the information associated with any errors that were detected. In a second example, OS 162 may query EC 190 for the information associated with any errors that were detected after OS 162 is executing via processor 120 or after OS 162 is executing via processor 120 and has achieved a point of execution where OS 162 may utilize and/or process the information associated with any errors that were detected. In another example, OS 162 may query EC 190 for the information associated with any errors that were detected after a user has logged in. For instance, OS 162 or an APP (e.g., an APP of APPs 164-168) may provide the information associated with the one or more errors to the user.

In one or more embodiments, at least one of the one or more errors may no longer exist and/or may no longer be an issue. In one example, a different power source may be coupled to IHS 110, such that the different power source provides enough energy such that an internal battery of IHS 110 may no longer be needed to power or power-in-part IHS 110. In another example, device 198 may be decoupled from IHS 110. In one or more embodiments, EC 190 may receive information indicating that the at least one of the one or more errors may no longer exist and/or may no longer be an issue. For example, if EC 190 receives or determines the information indicating that the at least one of the one or more errors are no longer exist and/or may no longer be an issue, EC 190 may remove information associated with the at least one of the one or more errors. In one instance, EC 190 may overwrite a portion of the one or more memory media that store the information associated with the at least one of the one or more errors. In another instance, EC 190 may modify the data structure that stores the information associated with the at least one of the one or more errors.

Turning now to FIG. 3, a method of operating an information handling system is illustrated, according to one or more embodiments. At 310, an error associated with an information handling system may be detected before an OS, executed via a processor of the information handling system, is operable to provide information associated with the error. In one or more embodiments, the OS may be operable to provide the information associated with the error at a point after the processor starts executing the OS. In one example, the point after the processor starts executing the OS where the OS is operable to provide the information associated with the error may include a point in executing the OS where the OS may communicate the information associated with the error. In one instance, the point in executing the OS where the OS may communicate the information associated with the error may include where the OS is operable to communicate via a port (e.g., a serial port, a network interface, etc.) of the information handling system. In another instance, the point in executing the OS where the OS may communicate the information associated with the error may include where the OS is operable to communicate the information associated with the error with a user. In one or more embodiments, the OS may be operable to communicate the information associated with the error with a user after the user logs in.

In one or more embodiments, EC 190 may detect an error associated with information handling system 110 before OS 162, executed via processor 120, is operable to provide information associated with the error. In one example, the error may occur during one or more of a POST and a boot-up sequence, among others. In another example, the error may occur after OS 162 starts executing and before the user is logged in (e.g., before the error can be displayed to the user). In one or more embodiments, the error associated with information handling system 110 may be associated with a device coupled to information handling system 110. For example, the error associated with information handling system 110 may be associated with device 198 coupled to information handling system 110.

At 315, information associated with the error may be stored. For example, EC 190 may store information associated with the error. In one instance, EC 190 may store information associated with the error via one or more memory media. In another instance, EC 190 may store information associated with the error via a data structure.

At 320, a query may be received. In one or more embodiments, a query may be received from a management information exchange. In one example, EC 190 may receive the query from MIE 163. In another example, EC 190 may receive the query from IHSFW 172. For instance, OS 162 may query EC 190 via querying MIE 163, which may query IHSFW 172, which may query EC 190. In one or more embodiments, OS 162 may query EC 190 after OS 162 is executing.

At 325, the information associated with the error may be provided. In one example, EC 190 may provide the information associated with the error to IHSFW 172. In a second example, EC 190 may provide the information associated with the error to MIE 163. In another example, EC 190 may provide the information associated with the error to OS 162. For instance, EC 190 providing the information associated with the error to OS 162 may include EC 190 providing the information associated with the error to IHSFW 172 which may provide the information associated with the error to MIE 163 which may provide the information associated with the error to OS 162. In one or more embodiments, providing the information associated with the error may include providing the information associated with the error to OS 162 when OS 162 is operable to provide the information associated with the error. For example, providing the information associated with the error may be performed in response to receiving the query from at least one of IHSFW 172, MIE 163, and OS 162.

At 330, it may be determined that the user is logged in. For example, OS 162, executing via processor 120, may determine that the user is logged in. In one or more embodiments, determining that the user is logged in may permit the information associated with the error to be provided to the user. At 335, the information associated with the error may be provided to the user. For example, the OS may provide the information associated with the error. In one instance, OS 162 may provide the information associated with the error via a display associated with information handling system 110. In another instance, OS 162 may provide the information associated with the error via a sound-producing device associated with information handling system 110.

At 340, it may be determined that the error is no longer an issue. In one example, EC 190 may determine that the error is resolved and/or is no longer an issue. In another example, the error may be associated with device 198 coupled to information handling system 110. For instance, EC 190 may determine that device 198 is not coupled to information handling system 110 and determine that the error is no longer an issue based on determining that device 198 is not coupled to information handling system 110.

At 345, the information associated with the error may be removed. In one example, EC 190 may remove the information associated with the error from the one or more memory media. In another example, OS 162 may remove the information associated with the error. In one instance, OS 162 may remove the information associated with the error from the display associated with information handling system 110. In another instance, OS 162 may no longer cause the sound-producing device associated with information handling system 110 to produce sounds associated with the error. In one or more embodiments, removing the information associated with the error may include modifying the one or more memory media that stores the information associated with the error. In one example, EC 190 may modify a data structure that stores the information associated with the error. In one instance, EC 190 may modify a flag and/or attribute, associated with the information associated with the error, of the data structure that stores the information associated with the error. In a second instance, EC 190 may overwrite one or more portions of the information associated with the error.

Although the description with reference to FIG. 3 describes an error, an event or other information may be substituted for an “error”, according to one or more embodiments. For example, EC 190 may store information that is not necessary associated with an error and/or an error condition. In one instance, a POST event and/or information associated with the POST event may be may be substituted for an “error” in the description with reference to FIG. 3. In another instance, information associated with a boot sequence may be may be substituted for an “error” in the description with reference to FIG. 3. In one or more embodiments, information from one or more of the POST and the boot sequence, among others, may be utilized in “playing back” information associated with a period of time of IHS 110 performing one or more actions.

Turning now to FIG. 4, another method of operating an information handling system is illustrated, according to one or more embodiments. At 410, an error associated with an information handling system may be detected after an OS is executing. In one example, EC 190 may detect an error associated with information handling system 110 after OS 162 is executing. In one or more embodiments, the error associated with information handling system 110 may be associated with a device coupled to information handling system 110. For example, the error associated with information handling system 110 may be associated with device 198 coupled to information handling system 110.

At 415, information associated with the error may be stored. For example, EC 190 may store information associated with the error. In one instance, EC 190 may store information associated with the error via a one or more memory media. In another instance, EC 190 may store information associated with the error via a data structure.

At 420, the information associated with the error may be provided. In one example, EC 190 may provide the information associated with the error to IHSFW 172. In a second example, EC 190 may provide the information associated with the error to MIE 163. In another example, EC 190 may provide the information associated with the error to OS 162. For instance, EC 190 providing the information associated with the error to OS 162 may include EC 190 providing the information associated with the error to IHSFW 172 which may provide the information associated with the error to MIE 163 which may provide the information associated with the error to OS 162.

In one or more embodiments, EC 190 may provide the information associated with the error to OS 162 upon detection of the error. For example, upon detection of the error may include a period of time transpiring between detecting the error and providing the information associated with the error to OS 162. In one instance, the period of time transpiring may be small. In another instance, the period of time transpiring may be within a few seconds.

At 425, the information associated with the error may be provided to the user. For example, the OS may provide the information associated with the error. In one instance, OS 162 may provide the information associated with the error via a display associated with information handling system 110. In another instance, OS 162 may provide the information associated with the error via a sound-producing device associated with information handling system 110.

At 430, it may be determined that the error is no longer an issue. In one example, EC 190 may determine that the error is resolved and/or is no longer an issue. In another example, the error may be associated with device 198 coupled to information handling system 110. For instance, EC 190 may determine that device 198 is not coupled to information handling system 110 and determine that the error is no longer an issue based on determining that device 198 is not coupled to information handling system 110.

At 435, the information associated with the error may be removed. In one example, EC 190 may remove the information associated with the error from the one or more memory media that store the information associated with the error. In another example, OS 162 may remove the information associated with the error. In one instance, OS 162 may remove the information associated with the error from the display associated with information handling system 110. In another instance, OS 162 may no longer cause the sound-producing device associated with information handling system 110 to produce sounds associated with the error. In one or more embodiments, removing the information associated with the error may include modifying the one or more memory media that store the information associated with the error. In one example, EC 190 may modify a data structure that stores the information associated with the error. In one instance, EC 190 may modify a flag and/or attribute, associated with the information associated with the error, of the data structure that stores the information associated with the error. In a second instance, EC 190 may overwrite one or more portions of the information associated with the error.

Although the description with reference to FIG. 4 describes an error, an event or other information may be substituted for an “error”, according to one or more embodiments. For example, EC 190 may store information that is not necessary associated with an error and/or an error condition. For instance, an even event and/or information associated with the event may be may be substituted for an “error” in the description with reference to FIG. 4. In one or more embodiments, information from OS 162 executing may be utilized in “playing back” information associated with a period of time of IHS 110 performing one or more actions.

In one or more embodiments, one or more of the method and/or process elements and/or one or more portions of a method and/or processor elements may be performed in varying orders, may be repeated, or may be omitted. Furthermore, additional, supplementary, and/or duplicated method and/or process elements may be implemented, instantiated, and/or performed as desired, according to one or more embodiments. Moreover, one or more of system elements may be omitted and/or additional system elements may be added as desired, according to one or more embodiments.
